Re: Scripting framework

[Vladimir Serbinenko <phcoder@gmail.com>]

I wrote the scripting support.
The patch can be found under http://phcoder.hut1.ru/bash.patch

As in this version there is no arithmethic support I added commands true5 and false 5 for testing
They return five times true and then false (true5) or inverse (false5)

TODO:
1) Positional arguments like $1, $2, ... and $*/$@ 
2) Arithmethic module for commands like ((2+3*5)) 
3) logical module for commands like [[ -f /boot/vmlinuz ]] 
4) break, continue and return commands
5) menu parameters like:
menu --default "Linux" { ... } 
Can anybody propose the way to generate menu entries from loop?
What about
menu --prepend var=val --prepend val=var ...
Then compiler will expand var=val and put it to the begin of menu
6) Regexp recognizer for case command

In difference with bash ( and ) are not the word separators. So you have to put spaces around them in case command
e.g.
case $x in ( 123 ) ....;; ... esac 
and not
case $x in (123) ....;; ... esac 
The same with functions.
e.g. hello ( ) { .. } 
or 
hello () { .. }
and not
hello() { .. }
Command select is not done. Menu should be enough.
Expansions and arrays are NOT the part of scripting but of split_cmdline and environment and is not made yet

Unfortunately I have now no more time. So I send this letter as is. More information will be available in my next letter and on the site.
